More than 80,000 metric tons of methane gas have spewed from the Aliso Canyon natural gas storage facility since October 23, causing thousands of Porter Ranch residents to leave their homes, and the closures of two schools where students are being bussed to campuses farther away from the gas. State officials are now concerned that a seventh attempt to plug the well may have increased the chance of a blowout, which would greatly increase the release of gas as well as the risk of a massive well fire if ignited by a spark.

The broken natural gas well in Los Angeles has been pouring methane into the air for nearly three months now. It’s estimated the Aliso Canyon leak has pumped 4.6 billion cubic feet of potent greenhouse gas into the atmosphere - as much as 1.3 million cars would in a year.

Now the spewing gas is sparking calls for a new watchdog system for methane. Ingrid Lobet of the investigative nonprofit inewsource reports.
